The Johnson-sims Feud: Romeo and Juliet, West Texas Style

Access: Use of this item is restricted to the UNT Community
In the early 1900s, two families in Scurry and Kent counties in West Texas united in a marriage of fourteen-year-old Gladys Johnson to twenty-one-year-old Ed Sims. Billy Johnson, the father, set up Gladys and Ed on a ranch, and the young couple had two daughters. But Gladys was headstrong and willful, and Ed drank too much, and both sought affection outside their marriage. A nasty divorce ensued, and Gladys moved with her girls to her father’s luxurious ranch house, where she soon fell in love with famed Texas Ranger Frank Hamer. When Ed tried to take his daughters for a prearranged Christmas visit in 1916, Gladys and her brother Sid shot him dead on the Snyder square teeming with shoppers. One of the best lawyers in West Texas, Judge Cullen Higgins (son of the old feudist Pink Higgins) managed to win acquittal for both Gladys and Sid. In the tradition of Texas feudists since the 1840s, the Sims family sought revenge. Sims’ son-in-law, Gee McMeans, led an attack in Sweetwater and shot Billy Johnson’s bodyguard, Frank Hamer, twice, while Gladys—by now Mrs. Hamer—fired at another assassin. Hamer shot back, killed McMeans, and was no-billed on the spot by a grand …

Out the Summerhill Road: a Novel

Access: Use of this item is restricted to the UNT Community
From Jane Roberts Wood comes a quietly riveting novel revealing the banal faces of evil in a small East Texas town. In 1946 a young couple is brutally murdered in Cold Springs. And, now, thirty-four years later, the rumor is that Jackson Morris, who had been the only person of interest in the murders, has come home. Or has he? When the four women of the Tuesday bridge club hear this rumor, their responses range from a reckless excitement to a shaky uneasiness. There’s Isabel, compelling and passionate, who foolishly and inexplicably longs to see Jackson, her first love, again while the seemingly innocent Mary Martha prays that the sheriff will put Jackson’s head in a noose. Although the eternally optimistic Sarah looks to the law to determine Jackson’s fate, the fourth woman, an Irish immigrant and a misfit in Cold Springs, is guided by the spirit world, including a cat, in deciding his guilt or innocence. When a second murder occurs after Jackson’s return, Cold Springs reacts with fear and paranoia while the women struggle to protect their friend’s reputation and desperately try to find a murderer.

Dynamics of microbial community composition and function during in-situ bioremediation of a uranium-contaminated aquifer (open access)

Dynamics of microbial community composition and function during in-situ bioremediation of a uranium-contaminated aquifer

A pilot-scale system was established to examine the feasibility of in situ U(VI) immobilization at a highly contaminated aquifer (U.S. DOE Integrated Field Research Challenge site, Oak Ridge, TN). Ethanol was injected intermittently as an electron donor to stimulate microbial U(VI) reduction, and U(VI) concentrations fell to below the Environmental Protection Agency drinking water standard (0.03 mg liter{sup -1}). Microbial communities from three monitoring wells were examined during active U(VI) reduction and maintenance phases with GeoChip, a high-density, comprehensive functional gene array. The overall microbial community structure exhibited a considerable shift over the remediation phases examined. GeoChip-based analysis revealed that Fe(III)-reducing bacterial (FeRB), nitrate-reducing bacterial (NRB), and sulfate-reducing bacterial (SRB) functional populations reached their highest levels during the active U(VI) reduction phase (days 137 to 370), in which denitrification and Fe(III) and sulfate reduction occurred sequentially. A gradual decrease in these functional populations occurred when reduction reactions stabilized, suggesting that these functional populations could play an important role in both active U(VI) reduction and maintenance of the stability of reduced U(IV). These results suggest that addition of electron donors stimulated the microbial community to create biogeochemical conditions favorable to U(VI) reduction and prevent the reduced U(IV) from reoxidation and that …

How People Actually Use Thermostats (open access)

How People Actually Use Thermostats

Residential thermostats have been a key element in controlling heating and cooling systems for over sixty years. However, today's modern programmable thermostats (PTs) are complicated and difficult for users to understand, leading to errors in operation and wasted energy. Four separate tests of usability were conducted in preparation for a larger study. These tests included personal interviews, an on-line survey, photographing actual thermostat settings, and measurements of ability to accomplish four tasks related to effective use of a PT. The interviews revealed that many occupants used the PT as an on-off switch and most demonstrated little knowledge of how to operate it. The on-line survey found that 89% of the respondents rarely or never used the PT to set a weekday or weekend program. The photographic survey (in low income homes) found that only 30% of the PTs were actually programmed. In the usability test, we found that we could quantify the difference in usability of two PTs as measured in time to accomplish tasks. Users accomplished the tasks in consistently shorter times with the touchscreen unit than with buttons. None of these studies are representative of the entire population of users but, together, they illustrate the importance of improving …

Bottom-up Representation of Industrial Energy Efficiency Technologies in Integrated Assessment Models for the Cement Sector (open access)

Bottom-up Representation of Industrial Energy Efficiency Technologies in Integrated Assessment Models for the Cement Sector

Adoption of efficient end-use technologies is one of the key measures for reducing greenhouse gas (GHG) emissions. How to effectively analyze and manage the costs associated with GHG reductions becomes extremely important for the industry and policy makers around the world. Energy-climate (EC) models are often used for analyzing the costs of reducing GHG emissions for various emission-reduction measures, because an accurate estimation of these costs is critical for identifying and choosing optimal emission reduction measures, and for developing related policy options to accelerate market adoption and technology implementation. However, accuracies of assessing of GHG-emission reduction costs by taking into account the adoption of energy efficiency technologies will depend on how well these end-use technologies are represented in integrated assessment models (IAM) and other energy-climate models.

Enforcing Building Energy Codes in China: Progress and Comparative Lessons (open access)

Enforcing Building Energy Codes in China: Progress and Comparative Lessons

From 1995 to 2005, building energy use in China increased more rapidly than the world average. China has been adding 0.4 to 1.6 billion square meters of floor space annually , making it the world’s largest market for new construction. In fact, by 2020, China is expected to comprise half of all new construction. In response to this, China has begun to make important steps towards achieving building energy efficiency, including the implementation of building energy standards that requires new buildings to be 65% more efficient than buildings from the early 1980s. Making progress on reducing building energy use requires both a comprehensive code and a robust enforcement system. The latter – the enforcement system – is a particularly critical component for assuring that a building code has an effect. China has dramatically enhanced its enforcement system in the past two years, with more detailed requirements for ensuring enforcement and new penalties for non-compliance. We believe that the U.S. and other developed countries could benefit from learning about the multiple checks and the documentation required in China. Similarly, some of the more user-friendly enforcement approaches developed in the U.S. and elsewhere may be useful for China as it strives to …

A Novel Low Thermal Budget Thin-Film Polysilicon Fabrication Process for Large-Area, High-Throughput Solar Cell Production (open access)

A Novel Low Thermal Budget Thin-Film Polysilicon Fabrication Process for Large-Area, High-Throughput Solar Cell Production

A novel thin-film poly-Si fabrication process has been demonstrated. This low thermal budget process transforms the single- and multi-layer amorphous silicon thin films into a poly-Si structure in one simple step over a pulsed rapid thermal annealing process with the enhancement of an ultrathin Ni layer. The complete poly-Si solar cell was fabricated in a short period of time without deteriorating the underneath glass substrate. The unique vertical crystallization process including the mechanism is discussed. Influences of the dopant type and process parameters on crystal structure will be revealed. The poly-Si film structure has been proved using TEM, XRD, Raman, and XPS methods. The poly-Si solar cell structure and the performance have been examined. In principle, the new process is potentially applicable to produce large-area thin-film poly-Si solar cells at a high throughput and low cost. A critical issue in this process is to prevent the excessive dopant diffusion during crystallization. Process parameters and the cell structure have to be optimized to achieve the production goal.

Characterization of soil water content variability and soil texture using GPR groundwave techniques (open access)

Characterization of soil water content variability and soil texture using GPR groundwave techniques

Accurate characterization of near-surface soil water content is vital for guiding agricultural management decisions and for reducing the potential negative environmental impacts of agriculture. Characterizing the near-surface soil water content can be difficult, as this parameter is often both spatially and temporally variable, and obtaining sufficient measurements to describe the heterogeneity can be prohibitively expensive. Understanding the spatial correlation of near-surface soil water content can help optimize data acquisition and improve understanding of the processes controlling soil water content at the field scale. In this study, ground penetrating radar (GPR) methods were used to characterize the spatial correlation of water content in a three acre field as a function of sampling depth, season, vegetation, and soil texture. GPR data were acquired with 450 MHz and 900 MHz antennas, and measurements of the GPR groundwave were used to estimate soil water content at four different times. Additional water content estimates were obtained using time domain reflectometry measurements, and soil texture measurements were also acquired. Variograms were calculated for each set of measurements, and comparison of these variograms showed that the horizontal spatial correlation was greater for deeper water content measurements than for shallower measurements. Precipitation and irrigation were both shown to …
